cannot install requirements

[vincentwi]

after conda create -n new_clean_env coda activate new_clean_env git clone https://github.com/facebookresearch/seamless_communication.git

I followed the README instructions and get the bellow error.

ERROR: Cannot install -r requirements.txt (line 4), -r requirements.txt (line 5), fairseq2 and torch~=2.1.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested torch~=2.1.0
    torchaudio 2.1.0 depends on torch==2.1.0
    fairseq2 0.2.0 depends on torch>=1.12.1
    fairseq2n 0.2.0 depends on torch==2.0.1

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

So I tried to install them individually following the fairseq installation, which was successful (be sure libsndfile is in your paths!), though fairseq installed torch 2.0.1, which was unsurprisingly later incompatible with torchaudio 2.1.0.

In the end I the relaxed the below in requirements.txt for a successful run of gradio app.py

torch~=2.0.1
torchaudio~=2.0.1

Not sure if it's worth a PR but thought to inform your team, and any others who reach the same issue.

Hey @vincentwi, thanks for opening this issue. I can confirm that this is a bug in the pre-built fairseq2n package for Mac. It accidentally depends on PyTorch 2.0.1 instead of 2.1.0. I am working on a fix now and will publish v0.2.1 of fairseq2 later today that fixes this.
